Fa'amatalaga o oloa
Methylparaben, o se vailaʻau faʻasolosolo ma le fua C8H8O3, paʻepaʻe tioata paʻepaʻe poʻo le tioata lanu, ma soluble i le ava malosi, eter, e matuaʻi soluble i le vai, vevela 270-280 °C. E masani ona faʻaaogaina e avea o se faʻasao faʻamaʻi mo le faʻaogaina o meaola, meaʻai, mea teuteu ma vailaʻau, ma e faʻaaogaina foi e fai ma fafaga fafaga. Talu ai ona o loʻo i ai se fausaga phenolic hydroxyl, o lona uiga antibacterial e sili atu le malosi nai lo le benzoic acid ma le sorbic acid. O lona faiga o le gaioiga o le: faʻaumatia le membrane sela o microorganisms, denature proteins i sela, ma faʻalavelaveina le gaioiga o enzymes manava ma faʻaogaina eletise eletise o sela microbial.

Galuega
O le pauta methylparaben e tele ona aoga, e aofia ai:
Sterilization ma antiseptic : Methylparaben ei ai se malosi antibacterial ma bactericidal aafiaga, e mafai ona faʻaumatia le sela sela o microorganisms, denaturate le porotini i totonu o le sela, ma faʻalavelaveina le gaioiga o le respiratory enzyme system ma le electron transfer enzyme system of microbial cell, e pei o e fai le matafaioi o le sterilization ma antiseptic. O lenei meatotino e faʻaaogaina lautele e fai ma faʻasao i meaʻai, mea teuteu, vailaʻau ma isi faʻalapotopotoga.
Anti-inflammatory and antibacterial : I le faaopoopo atu i le avea ma se faʻasao, o le Methylparaben e iai foʻi aʻafiaga faʻamaʻi ma antibacterial ma e mafai ona faʻaaogaina e togafitia ai faʻamaʻi pipisi o le paʻu, e pei o le mageso o le paʻu, mageso o le paʻu ma isi faʻaʻailoga le lelei. I le faʻaogaina lelei, o le methyl p-hydroxybenzoate o loʻo iai ni aʻafiaga i le paʻu.
Mo le faʻaogaina o meaola: Methylparaben e mafai ona faʻaaogaina e fai ma mea mata mo le faʻaogaina o meaola, aemaise lava ona esters, e pei o le methyl paraben, ethyl paraben, ma isi. mea manogi, fualaau 'aina ma fualaau faisua, fa'asao mo oloa piki .
Fa'aoga ile vaila'au ma mea fa'alelei : O le Methylparaben e fa'aaogaina e fai ma fa'asao i vaila'au ma mea teuteu e puipuia ai mea'ai mai le pala po'o vaila'au mai le leaga. I cosmetics, e mafai ona puipuia mea teuteu mai le pala, pala, ma faatumauina le fou ma le aoga o oloa .
Isi fa'aoga : Methylparaben o lo'o fa'aogaina fo'i e fai ma mea vavalo i vali, vaila'au fa'ato'aga, ma vaila'au fa'ato'aga mo le tu'ufa'atasiga o iniseti organophosphorus. E le gata i lea, o loʻo faʻaaogaina i le gaosiga o polymers tioata vai ma palasitika, ma o se phenol derivative o le benzoic acid, e mafai ona faʻalavelaveina le tele o siama gram-positive ma nisi siama gram-negative 4.
I le aotelega, o le Methylparaben paʻu e le gata o se faʻasao lelei ma le antibacterial agent, ae o loʻo i ai foi se sao taua i le faʻaogaina o meaola ma isi fanua.
Fa'aaogāga
Methylparaben, e lauiloa foi o le methyl paraben poʻo le methyl hydroxyphenyl ester, o se paʻepaʻe tioata paʻepaʻe poʻo se tioata e leai se lanu, solu i le ava malosi, ether ma le acetone, e matuaʻi soluble i mea vai, o le vevela o le 270-280 ° C. O le faʻaoga autu o lenei mea. tuufaatasiga e aofia ai:
Organic synthesis : E avea ma mea masani o le organic synthesis, faʻaaogaina e faʻapipiʻi ai vailaʻau eseese.
mea'ai faaopoopo : fa'aaogaina e fai ma fa'asao fa'ama'i e puipuia ai mea'ai mai le pala ma fa'aumi ai le fa'aola o mea'ai.
Cosmetics : I le avea o se faʻasao faʻamaʻi o mea teuteu, tausia le tumama ma le lelei o mea teuteu.
metila p-hydroxybenzoate o loʻo faʻaaogaina e avea o se faʻasao faʻamaʻi i totonu o fale gaosi oloa e faʻamautinoa ai le saogalemu ma le aoga o vailaʻau.
Fafaga fa'asao : fa'aaogaina i fafaga e puipuia ai le tuputupu a'e o meaola ninii ma fa'amautinoa le lelei ma le saogalemu o fafaga.
E le gata i lea, o le methyl p-hydroxybenzoate o loʻo i ai foʻi se faʻalapotopotoga o le phenolic hydroxyl, o lona uiga e sili atu le malosi o lona faʻatinoga o le antibacterial nai lo le benzoic acid ma le sorbate, lea e mafai ona faʻaumatia ai le sela sela o microorganisms, denature proteins i totonu o sela, ma faʻalavelaveina gaioiga o le manava manava. faiga ma le eletise fesiitaiga enzyme faiga o sela microbial, ina ia ausia le faamoemoega o le anti-corrosion. O lenei tuufaatasiga e masani ona faʻaaogaina i le tele o faʻalapotopotoga ma o se vailaʻau taua tele.
